Nope. The lab alone weighs 3.5t. That's 17 Science Jr's. They are big and clunky, but light (comparatively) That's a lot of biomes/locations. That's also not taking into account the dV used from flying the lab out there, then flying to/from the lab and then back to another moon/location (for a max of 40% of the points), or then then flying the lab *back* to kerbin (especially when you can just dump the used goo canisters/materials bays and store the results on your lander capsule for 100% returns). This is especially true when you account for the extra stuff needed (RCS fuel, ports) for docking, electricity and transmit antenna for the lab, solar cells, control (either probe core or *another* pod+crew), etc and the real life *time* needed for docking and rendevous. Again, the math isn't there for using it, ever, really. As per the return, kerbal EVA's can take the results, and store them in said .8t capsule. I wish it was useable. I really do. KSP *needs* a reason for rovers and stations...or at least I wish it did.
